I worked in the landscape department for Grosvenor and can say that many of the jobs they make you do are pointless.
My typical workday was generally a mess and never kept to schedule, I learnt very little whilst an apprentice with Grosvenor, it seems that they just give up on you and want to use you as a cheap labourer.
The work team is very clicky and don't allow you in their circle, evryone has little to no motivation to work making the job a miserable atomosphere, to top it off the management try to rule the team with a dictatorial iron fist, and if things aren't going the way they want it, they threaten your job.
The hardest part of the job is actually finding the motivation to work, especially with a team that just has no motivation.
The most enjoyable part of the job is working alone, when you don't have any of the team trying to interfere with your day to day jobs and moan about the management.
