I don’t think in any circumstances can Musk be regarded as a “ nice guy “. He brilliant , creative , adventurous, mad as a hatter , unconventional etc. but “ nice “ is not an adjective that is easily applied to him . His attitudes to employees is rather bizzare , his actions in Twitter had him fall immediately foul of Irish employment law at a twitters European HQ and it will cost him a packet in compensation when the employment court rules in favour of the dismissed employees which they will 100 % surely will anyone with significant service years will get big money in compensation or could be forced by the courts to be rehired. You just can’t fite people like that.
Musk clearly was badly advised or choose to ignore it. I presume he doesn’t care about thd 100000k in compensation his actions will cost Twitter Europe , it will also mean the labour courts will look extremely carefully at any subsequent layoffs and could levy Twitter with enormous fines , the labour courts have huge powers and they take it seriously they could in effect completely prevent arbitrary layouts without significant reasons in future. In fact it could force Elon to move the operation to another country but in the EU the labour laws simply prevent this type of reasonless layoff approach without significant compensation resulting.
