Firstly, yes, far too much-take this as a learning experience, no company would employ anyone even if they were perfect for the job, if they ever sent an email like that.
you really shouldn't have sent the email
first things I learnt getting a graduate job are;
1-HR can ALWAYS be counted on being useless. It's a fact
2-No-one owes you anything
These are hard things to hear and to learn-we spend our childhoods being told that being a good person will reap rewards. It doesn't. I've seen horrible people becoming successful, rich etc and the kindest, sweetest people having to borrow money to pay the rent. It's horrible-while there are genuinely kind considerate people out there who will help, many MANY more won't-out of pure selfishness. Sorry to tell you but get used to it.
I've broken down your post and commented on specific parts;
"I made a lot of effort in my application"-who hasn't?? I had to wait 6 months to stop doing shop work and actually get a graduate job, I have tonnes of experience, a DBS, a 2:1 from a decent college but for whatever reason I have only just got a job in a local college. They don't want to hear this. That's like someone writing I know this exam essay is rubbish but I really did work hard and revise all year! I need 70% so what do you say? This is just as ridiculous as that.
"I was at least expecting a standard rejection email, as a matter of common courtesy." Don't expect anything from a potential employer. I heard a great quote when job hunting "you don't have the job until you get your first pay check" yes there are people who exploit you and you do the work but aren't paid properly-FYI small claims courts are free and if you have a clear case with evidence you will often win. But for everything else, the employer has total control, You've just demonstrated that you throw your toys out of the pram and that they should never employ you.
"I have been a loyal Volunteer" In a letter like this, this is irrelevant-leave this with the CV
"the cold weather and lack of heating" this is not HRs problem, Email someone else about this-what were you hoping to gain from this comment?
"my emails have so far gone completely ignored" see above
"it wouldn't have taken you much time" you are right and it is frustrating, but again it's not their problem and they owe you nothing.
"I believe I could have been a good employeeI" firstly 'good' is always a terrible adjective-sorry English Tutor habits! secondly, who cares? you're not exactly going to write-you're right! I am a theif anyway...
"will not put myself through the trouble of applying again". when they read this they are probably so p***ed off at this point they are thinking YES please DON'T!!
The world of work is cut throat, hard and brutal, and emails like this are best drafted in fury, deleted and replaced with something like
"Dear Sir/Madam
RE: Application for the role of...
I recently applied for the role of X but have had no response, I have attached a copy of my application form in case it has been lost, misplaced etc.
If it has not been lost and I did not qualify for an interview I would welcome any constructive criticism for any future applications I make.
I continue to enjoy my role as a volunteer in your organisation and am enthusiastic about the work of this organisation.
I appreciate you are very busy and I may not receive a response,
Many thanks
Your name.
You've achieved everything you've wanted to;
you've raged,
you've asked about your application,
you've asked how you can improve
most importantly you haven't shot yourself in the foot.
We've all done daft things out of a sense of injustice/rage when we are young-the best thing to do now is to leave well alone and learn from this mistake
I once called a teacher out for bullying when I was 18 working as a teaching assistant in front of the entire department and our boss.
she hated me until she left and many others distanced themselves.
I should have gone to our boss and asked him to keep an eye out/made a formal complaint
I worked there for three years and luckily it was proven to be true and after making friends with many in the department-it took me AGES to gain their trust-I managed to apologise and they laughed and commented that I have really matured and grown up since they first met me-my boss is now a good friend and I relied on him when getting my latest job for a reference.
I was VERY lucky, you just have to accept you haven't been this time, learn from it and accept it is a part of growing up.
sorry to sound so harsh I just want to help x
