Part of the reason for the strikes is that HP - Enterprise Services (formally EDS) Is the only section in the company with year on year profit increases from last year and the year before.
If HP had not purchased EDS then it would be seeing a 20% year on year drop in profits. Rather than a (marginal) increase in profits year on year. -Note I said Profit not revenue. a 20% drop in profit is still a profit.
Yet it is HP Enterprise services that has had to take 2 years of pay freezes (the rest of HP were entitled to Pay rises and a bonus last year EDS wasn't) a 5 % paycut (followed by a further 10% paycut in the US for one month) and 80-90% of the layoffs HP has made. The HP Manufacturing sections have been largely untouched in the whole affair.
Another fact to consider is that The IT service industry is largely untroubled by short term recessions due to the length of contracts with customers, and the fact that other companies which are looking to make cutbacks will turn to outsourcing their IT. The CEO of HP said as much about this time last year.
So HP Enterprise Services Staff feel bloody hard done by that they are contributing the majority of the success of the company, they are the ones who are enabling the massive executive bonuses ($42 million for the CEO last year), they are the ones which are making a massive contribution to the Share price rising over the last 2 years rather than dropping.
The simple fact is there is no justification for the actions being taken other than corporate greed. HP is making more profit than it did last year, and more profit than the year before, before the Credit Crunch and Recession had occurred.
The Employees of HP Enterprise Services have every right to feel hard done by and every right to take industrial action to draw attention to the fact that they are unhappy with the direction the management is taking the company.
