I have worked on my own laptop for a while (due to startup lack of money, it was either wage or the laptop at some point due to liquidity issues), with one point made to my employer: All copyright on work done on my laptop belongs to me, and only me. You can 'rent' it by paying me my wage but as soon as I leave, all code on it is mine and I'm taking it with me for future 'reference'. Don't know how this works legally but since I'm not a self employed person who has a business contract, I'm pretty sure you cannot legally force someone to use their own stuff without compensation.

I told them they could pay me a compensation (for using/bringing my own tools) but that is quite expensive since most deductions don't count for this. Even more expensive than buying a proper laptop. Quite quickly I got a proper company laptop after finances improved to resolve the issue.

On another note:

In my experience the term 'middle management' is a synonym for corrupt, useless idiots so getting rid of them saves huge amounts of money since they add no value to any product or to the company as a whole. Unfortunately there is no way to even moderately grow within most companies around here except for a management track which is idiotic since specialists are way more valuable to the gross product of the company.

and: Never underestimate the value of skilled workers and how to keep them or train them. In software they are your main business. Everything else is easily replaceable.
