You require to work remotely? Most managers cannot stand that - if you aren't there in the office so they can see that you are working, you must be goofing off, you cannot possibly be working. Judge you by your results? They wouldn't know how to do that, and they are far too harrassed/unimaginative/untrained to work out a method of doing it.
I've been in IT for more than 40 years, a contractor for the last twenty. In all that time, I have once had one contract that allowed me to work from home, and then it was just one day a week - and even then, in the middle of the contract, they tried to change it to all five days a week.
