@TalkLessSmileMorePlease the thread was summarised 'Should I just shut up at work?'. You've received some fairly extreme views from both sides of the discussion.
To recap:
you are in a junior role paid £10/hour or so;
you regularly identify inefficiencies or opportunities to improve existing processes from your perspective in the team;
you speak up for colleagues who have a moan to you about their operational problems too.
None of these attributes is problematic of itself. Consider the balance though:
you were recruited to a £10/hour role where, presumably, the tasks required of you and the time required to complete these tasks each day/week is fairly well defined;
you are 'encouraged' by your line manager to pursue your suggestions -indeed some have been implemented- but you still end up sending a nearly monthly email to management on suggested improvements;
your colleagues don't speak to back up their issues you've raised on their behalf in meetings.
This suggests there are probably 3 middle of the road options to address each of these major points:
- Discuss with your line manager what is expected to be achieved by you in your role and how much scope there is for process improvement. Telling you not to take it further suggests a line manager is not interested in you showing them up as not having noticed simple improvements themselves. Yours appears to be giving you enough rope to hang yourself though -encouraging you 1-2-1 but not backing you up in how to raise this up the chain for effective change management. This suggests they are probably weary of the pace of suggestions you raise, OR you haven't listened to their input on the much raised point here 'choose your battles'. Are you able to have a monthly 1-2-1 session which (briefly!) covers off your latest great ideas, and then your line manager helps you identify ones which are worth taking forward? Then set out the additional steps you need to take to impact assess your idea on other teams' work/resource needed to implement/who to consult/how best to raise it to achieve success. A good line manager would help coach you through this process. Unless of course they think "ffs I've just hired someone at £10 an hour to do the scanning and phones, I don't care if they could save 10 minutes a week walking to the stationery cupboard to get leaflets when needed - keeping them there means 500 leaflets a month aren't nicked off front desk and saves us £ hundreds in reprinting". You haven't positioned the nature of your suggestions, so the reality could be anywhere on this spectrum.
- You could be tone-deaf to your line manager's existing feedback on which points are worth pursuing and they have already reached the 'smile and nod' stage in dealing with you - suggesting you email more senior managers rather than crushing your enthusiasm with a more direct NO. Fine tune your listening skills and try to determine why you are pursuing a fruitless approach of monthly emailing. Again, pick your battles! Figure out what your line manager can really get behind so your time writing up suggestions is better spent, and the outcome more fruitful. Paring things down will mean the more important items are more likely to be listened to, taken seriously, and acted on. As others have said, gather information about the impact on others' work as well as your own and propose a rounded solution.
- Again, as others have said, fight your own battles. You haven't been hired as a process improvement consultant, and while others' moans might or might not add to business efficiencies, you don't need to advocate for them. Focus on what helps you to deliver your own role well - and better - and leave it at that until you've been asked to look more widely for improvement targets as a result if your track record.
If you think that more training in this area could lead to a career switch, go for it!
But if you think having the bright ideas, and telling 'managment' to fix them is how it works, button it and do what you have been hired for!
I'm the first person to support process improvements and personal development through training.
It's also entirely possible you are just a whiny PITA to manage.
Both extremes are possible - reflect on yourself and decide where on the range you sit, and what personal change you are going to implement to move things on...
